Muted mp4 Videos play unmuted when viewed on a mobile device
I have several slides in my story that include muted video footage as a visual backing to my narration. The video format is mp4. I import the video, add any captions necessary etc and then mute the video's sound, recording an audio track for the narration which is the only thing learners will hear.
When the published story is viewed on a PC, it performs perfectly. Learners can see the footage, and hear only the narration.
However, when viewed on an iPad, using the Articulate player, these videos, wherever they appear in my story, all mysteriously become unmuted, which shatters my narration.
I can't see any related threads on here so far. I would really appreciate some advice on how to solve this, thanks!
